public bool HasModifiers (Android.Views.MetaKeyStates modifiers);

[<Android.Runtime.Register("hasModifiers", "(I)Z", "")>]
member this.HasModifiers : Android.Views.MetaKeyStates -> bool

Parameters

modifiers: MetaKeyStates

The meta state of the modifier keys to check. May be a combination of modifier meta states as defined by #getModifierMetaStateMask(). May be 0 to ensure that no modifier keys are pressed.

Returns

Boolean

True if only the specified modifier keys are pressed.

Attributes: RegisterAttribute

Exceptions

IllegalArgumentException

if the modifiers parameter contains invalid modifiers

Remarks

Returns true if only the specified modifiers keys are pressed. Returns false if a different combination of modifier keys are pressed.

For the purposes of this function, #KEYCODE_CAPS_LOCK, #KEYCODE_SCROLL_LOCK, and #KEYCODE_NUM_LOCK are not considered modifier keys. Consequently, this function ignores #META_CAPS_LOCK_ON, #META_SCROLL_LOCK_ON and #META_NUM_LOCK_ON.

If the specified modifier mask includes directional modifiers, such as #META_SHIFT_LEFT_ON, then this method ensures that the modifier is pressed on that side. If the specified modifier mask includes non-directional modifiers, such as #META_SHIFT_ON, then this method ensures that the modifier is pressed on either side. If the specified modifier mask includes both directional and non-directional modifiers for the same type of key, such as #META_SHIFT_ON and #META_SHIFT_LEFT_ON, then this method throws an illegal argument exception.
